CUNY Academic Commons

I think the problem is that BuddyPress-wide uploaded files (documents, etc) are being stored in blogs.dir/1/files and thus being counted against blog 1's storage limit. There are a few solutions:
1) Turn off the blog upload space check (Site Admin > Options). This can be done right away.
2) Write a snippet that skips the blog storage space check for blog 1. This isn't too hard but it will have to wait for 1.0.2.

FWIW I think the way that file uploads are handled, especially on blog 1, is changed pretty radically in WP 3.0. So it might not be worth putting a ton of time into the issue. But I do see a way to fix it with just a line or two of code.

Side note: This doesn't affect the ability of BuddyPress plugins to upload to this space, because those uploads don't get run through wpmu_checkAvailableSpace, while Dashboard > Media > Add Media does. Essentially, the fix involves unhooking that function on blog_id = 1.

I'm going to set the ticket to Hold with a target version of 1.1, in the hopes that upgrading to WP 3.0 will make the problem go away magically. In the meantime, if you want to upload images for use on the main Commons blog, upload them to a different blog (like the News blog) and hotlink.

Fixed in https://github.com/castiron/cac/commit/41dd62b8bae3a8aafa048736f529aa0933f97e11

https://github.com/castiron/cac/commit/4141dacc0a308ce383a5c573f6860fcc0912474c should ensure that the fix sticks after we've upgraded to 3.0. If it doesn't work, please reopen the ticket.
